摘要：

An analytical method for determining proanthocyanidins by HPLC-electrochemical detection was developed, and the effect of free radicals on chill haze formation in beer was studied. The determination limits of procyanidin B3, catechin, and epicatechin by this analytical method were 30, 10, and 10 ng/ L, respectively. Addition of H2O2 and irradiation with 60Co 7-rays accelerated the degradation of the proanthocyanidins and formation of chill haze in beer, while the addition of a metal scavenger, a H2O2 decomposer, and free-radical scavengers inhibited these phenomena. Therefore, it was speculated that free radicals generated by Fenton and Haber-Weiss reactions in beer could play an important role in chill haze formation. © 1990, American Chemical Society.
